Answer:
The P(yellow) = 11/15
Step-by-step explanation:
Here, we have;
P(not yellow) = 4/15
Mathematically, the addition of the probability of an event and its complement adds up to be 1
The complement we have here is P(yellow)
Thus, mathematically we have;
P(not yellow) + P(yellow) = 1
P(yellow) = 1 - P(not yellow)
From the question P(not yellow) = 4/15
Plugging this value, we have;
P(yellow) = 1 - 4/15 = 11/15
on 22 liters of fuel: aprox 1.8 km
999/80 = 22/x
999x = 80x22
x = 1,782/999
x=1.783783783(
x= aprox 1.8 km
Answer:
A. 57.2
Step-by-step explanation:
Given: Nelly runs = 10-mile race in 88 minutes. At the same rate but 6.5-mile race
To find: How long it would take him to run a 6.5-mile race
Solution: To calculate the how long;
<u>How to calculate running pace</u>
- Divide your run time by your distance
- If you ran 3 miles in 30 minutes: 30 min ÷ 3 mi = 10 minutes per mile pace
<u>How to calculate run distance</u>
- Divide your running time by your pace
- If your pace is 8 minutes per mile and you ran for 32 minutes: 32 min ÷ 8 min per mi = 4 miles
<u>How to calculate run time</u>
- Multiply your pace by your distance
- If your pace is 9.5 minutes per mile and you ran 3 miles: 9.5 min per mi × 3 mi = 28.5 minutes = 28 minutes, 30 seconds
<u>How to calculate running speed</u>
- Divide your run distance by your run time
- If you ran 2.5 miles and you ran for 20 minutes:
2.5 mi ÷ 20 min = 0.125 miles per minute
Xy - x - y + 1
explanation: distribute (x-1)(y-1) —> x(y-1) - 1 (y-1) —> xy - x - 1(y-1) —> xy - x - y + 1
